The Galaxy of Star Wars fandom had a collective moment of weakness around the time TFA came out. I think people were just glad there was a film coming out that everyone was hoping would wipe the bitter taste of the PT from thair collective pallets. And somehow in the heady concoction of Star Wars revival combined with the Holiday season, fans managed to forgive the PT; especially those who were kids at the time the PT were released.
But anyone who believe the PT were, in retrospect, good are fooling themselves.
